Boost Your WiFi Signal With Print-Out DIY Foil Reflectors

Whether you've got a monster mansion or just a small place with thick walls, you might see that your WiFi signal starts dropping off when you're farthest away from your router. The WiFi signal is powerful stuff, sure, but every wall and obstacle it hits gives it a bit of interference—meaning you, trying to stream Netflix on your laptop from your bedroom, might not have the strongest signal. Good news, though: There's an easy (and super cheap!) way to give your WiFi a sizeable boost: Grab your printer and a roll of aluminum foil.

Need a little extra power from your wireless router? Just turn to that wonder of mathematics and physics: The parabola.

But don't worry—you won't have to do any kind of calculations for this project. FreeAntennas.com has prepared a printable template to create a reflector the perfect size and shape for your router's antennas.
